Properties of Paint
Pigments (for colour) Ex. Whitewash/whitening (Calcium Carbonate)
Binders/ Film Formers (holds pigment particles together)
Solvents (the liquid, so paint spreads evenly and penetrates into surface)
Types of Paint
Buying INTERIOR Paint
Milk paints: made from milk proteins
Natural paints: derived from citrus, minerals, etc
Latex paints: low biocides and VOCs levels
Remember to keep painted room well-ventilated!
good adhesion qualities = hard, durable finish
attractive, glossy finish
oxidizes, chips, and yellows over time
requires a longer time to dry
higher percent of VOCs (40%-60%)
good resistence to brittling/ crackling + good colour retention = lasts longer
lower percent of VOCs (5%-10%)
releases emissions that creates "bad" ozone = greenhouse gas effect and global warming
inhalation may lead to eye, nose, and throat irritations
long term health issues: kidney, heart, lung damage
Heavy Metals= High Toxicity Levels
Lead: added to increase durability, speed drying, and resist moisture
Chromium: used as paint primer for tough protective coating
used to extend shelf life: kills microorganisms in paint
pollutes indoor air
if not disposed properly, can seep into ground water = hazardous contamination
Things To Look For:
Things to Avoid:
Ways to Lessen Harmfulness
Old cans: may contain mercury/ lead
Never pour paint down the drain (some of the chemicals can’t be treated/removed) results in water contamination
Never throw paint in the trash (not allowed in landfills) can contaminate ground water
Drop unused/leftover paint at a Household Hazardous Waste Collection Facility
Oil-based/solvent paints: high VOCs level
Brands to Try:
Cil Dulex Natural Whites
Benjamin Moore Paints
Boomerang- Recycled Paint
Effects on the Environment
Buying EXTERIOR Paint
Lead can get into air, water, and soil
Soils near cities have higher lead concentration
Plants absorb metal dust through their leaves, and from soil
--> <250g/l or <380g/l
